Oracle Database 11g: Introduction to SQL
Oracle Database 11g: SQL Fundamentals I
Pédagogie
The SQL Tuning Workshop class covers investigative methods that reveal varying levels of detail about
how the Oracle
database executes a SQL statement. Students learn the different ways in which data can be accessed,
which ones are
most efficient under specific circumstances, and how to ensure that the best method is used.
Partitioning topics are
covered, in addition to taking advantage of hints, bind variables, and different types of indexes.
This course counts towards the Hands-on course requirement for the Oracle Database 11g
Administrator Certification.
Only instructor-led inclass or instructor-led online formats of this course will meet the Certification
Hands-on
Requirement. Self Study CD-Rom and Knowledge Center courses DO NOT meet the Hands-on
Requirement.
Learn to:
Identify Poorly Performing SQL
Understand the Query Optimizer
Trace applications
Monitor SQL execution in real time
